I think the answer is much simpler:
F in the result has to be 1 (carry), the rest is automatic
 
   ELF		 721
 + ELF		 721
________	   _______

  FOOL		1442

LOL,

The brute force solution in AFL.  I have solved many problems this  
way with BASIC, APL, etc.

However, looking at this problem, it looks more like a logic problem  
than a math problem.

You get a big hint because:
F+0 = L therefore L= F
E +0 +carry = F therefore E = F - 1
substituting you get:
  c       c
  F-1   F      F
           F-1  F    F
---------------------
F     2F    2F    F

to make a carry:  2F > 10  therefore F>4 and O = 2F-10
L&F = 5, E = 4, O = 0
L&F = 6, E = 5, O = 2
L&F = 7, E = 6, O = 4
L&F = 8, E = 7, O = 6
L&F = 9, E = 8, O = 8

Fun one,
Dennis
